Specification of Letters Patent.

Application filed February 24, 1915. Serial No. 10,276.

To all whom it may concern Be it known that 1, GRANT T. DAVIS, a citizen of the United States, and a resident of Clinton, in the County of Lenawee and State of Michigan, have invented a new and Improved Internal-Combustion Turbine, of which the followingis a full, clear, and exact description.

This invention relates to improvements in devices for producing pressure by'combustion, and has for an object the provision of an improved structure which will continuously produce pressure by internal combustion for use in operating a continuously moving turbine or other steamoperated devlces.

Another object of the invention is to provide a combustion chamber and a turbine chamber in axial alinement therewith togetherwith means for supplying fuel and air in correct proportion to the combustion chamber whereby there will be produced a proper combustion, this chamber being also associated with a water inlet construction for supplying water which is utilized in Jabsorbing most of the heat units for producing steam pressure, whereby the turbine is actuated.

A further objectin view isto provide a device for continuously supplying steam under pressure through the instrumentality ofan internally fired boiler.

In the accompanying drawings Figure 1 is a longitudinal vertical section through a device embodying the invention; Fig. 2 is a sectional view through Fig. 1 on line 22.

Referring to the accompanying drawings by numerals, 1 indicates a base-on which is arranged a tank 2 for containing fuel of some kindv as for instance hydrocarbon oil.

1 This tank me be integral with base 1 or the ower ulle 56. p p Y separate as desired. A tank 3 is provided adjacent tank 2 which acts asian air reservoir, the same being formed in any desired manner, as for instance integral with base 1 and tank 2. An air pump 4 is arranged in the tank 3 for maintaining any deslred pressure of air in tank 3. The pump 4 is actuated through a worm gear 5 and a crank mechanism 6 of substantially any preferable kind as shown more particularly in Fig. 1, whereby the pump 4 operates in timed relationship to the movement of the shaft 7. and

8'. An opening 9' is provided between tanks 2 and 3 so that an air pressure may be exerted on the fuel in tank desired form of slip joint.

3 and the same forced through the feedpipe 9 t0 the burner 10 where the same is mixed with air fed to the burner 10 through pipe 11 from tank 3. A valve 12 is provided in pipe 9 for regulating the fuel so that the amount of fuel and air fed to burner 10 will be in proper proportion for allowing a proper combustion in chamber 13. The burner 10 is provided with a valve 14: of any desired construction whereby the burner may be turned on and-off. When the burner is first turned on the combustible mixture is ignited by a spark from a suitable spark plug 15. Usually the flame is maintained burning by a continuous supply of com- Patented Now-16, 1 9151 bustible matter, but if for any reason the flame should go out, the same may be easily lgnited by a spark from plug 15L It is to-be noted that the flame from burner 10 burns into chamber 13 in sprays distributed over a In order that this may be large surface. readily done, and also continuously performed, the shaft 7 of the turbine 17 is hollow. As shown in Fig 1-, a casing 18 is provided which is in the nature of a water jacket, which water jacket supplies water to pipe 19, and 'pipe 19 is connected with the shaft 7 at 20 through the provision of any The water passing through'the turbine will be warm as the same is taken from thewater jacket 18 and is sprayed in this condition by a nozzle 21,

and also by a plurality of 'almost radial apertures 22. The nozzle 21 is arranged directly in the end of the hollow shaft 7, while the apertures or bores 22 extend from a point back of the end of the turbine to the periphery adjacent the edge. The discharge points of the apertures or bores 22 are so positioned that the discharge from all y of the bores will be against a rounded surface 23.which may be formed integral; with the walls of chamber 13, or may be a separate ring inserted at this point. As shown in Fig. 1, the deflecting ring 23 deflects the water from bores 22, "and in deflecting the same causes a form of fanto be produced,

that is,'a spreading of the water. Aspread ing or spraying of the water by the ring member 23 produces an encircling housing of vapor around the flame, and byreason of being finely .divided the heat from the flame and the surrounding walls of the chamber quickly turns the vapor or sprayed Water into steam. The nozzle 21 also produces a substantially conical shaped spray which surrounds one end of the flame and is convertedinto steam by the heat substantially as fast as the spray is forced into chamber 1.3. It is evident that the spraying of water into chamber 13 must be in proper proportion-to the heat provided by the burner 10 so as to produce steam, and also'to produce the steam at the desired pressure.

- The detailed construction of the turbine 17 may be of any kind as the same forms no part of the present invention, andalso the turbine may be arranged to receive steam from either end. In the drawing a supply pipe 24 is provided for directing the steam to an inletheader 25 so that the steam will be fed to the blades of the turbine and finally discharged out the discharge header 26 which may be led to anyconvenient point. The turbine. 17 is of course connected with the shaft 7 .forrotating the same, whereby power may be transmitted to pulley 8 which is rigidly secured thereto, and from pulley 8 to any device.

The invention contemplates the provision of meansffor producing steam through the utilization of a flame in an inclosed chamber. This steam is shown in the draw ng as being supplied to a turbine, but the steam 27 is closed and va lve28 is opened so that the steam may pass through pipe 29 to t he discharge device which is intended to utilize thev steam. If itis desired to discharge a certain quantity of steam through pipe 26,

andalso to operate the turbine 17, both valves 27 and 28ar'e opened.

In the drawing one adaptation of the invention has-been disclosed, but it will be evident that a large number of variations may be-used'without departing-from the 5:1v

substituting some other'd'evic'e for the turbine 17 and. rearranging the various other spirit "of the invention, as for instance by parts-so as to adaptthe device to different locations) and different conditions. It will alsobe evident that the sprays from, the

waterf'jets will protect the side walls of chamber 13 and prevent" any overheating thereof.
